Radon and thoron exhalation rate, emanation factor and radioactivity risks of building materials of the Iberian Peninsula [PDF]
PeerJ, 2020 Radon (222Rn) and thoron (220Rn) are radioactive gases emanating from geological materials. Inhalation of these gases is closely related to an increase in the probability of lung cancer if the levels are high.

Radon-thoron measurements in air and soil from some districts of northern part of India [PDF]
Nuclear Technology and Radiation Protection, 2015 Radon, thoron and their progenies in the indoor environment are considered as one of the health hazards. The alpha emitting nature of these gases made it possible to detect in indoor environment with the help of nuclear track detector techniques.

The method for recalibration of thoron concentration reading of RAD7 and obtaining the thoron exhalation rate from soil surface [PDF]
Nuclear Technology and Radiation Protection, 2013 Thoron exhalation rate can be obtained through the combination of the “accumulation chamber” technique and RAD7. Thoron’s rapid decay causes the intake path and the air flow rate to become important factors in calibration.

Environmental radon, its exhalation rates and activity concentration of 226Ra, 232Th, and 40kK in Northern India [PDF]
Nuclear Technology and Radiation Protection, 2020 Human beings are constantly exposed to radioactivity in the environment. As they are major sources of harmful radiation, radionuclides found in the atmosphere might result in a substantial potential risk to living beings. On the Earth's surface,
